THREAD-GUIDE.

To aZZ whom, it may concern.-

Be it known that I, ISAAC E. PALMER, a citizen of the United States, and a resident of Middletown, in the county of MiddleseX and State of Connecticut, have invented a new and useful Improvement in Thread-Guides, of which the following is a specification.

My invention relates to thread guides and more particularly to thread guides for use in connection with spinning or twisting machines, the object being to provide a simple and inexpensive guide which may be adj usted universally in a horizontal plane to bring its eye in exact alinement with the axis of the spindle in connection with which it is intended to cooperate.

In the accompanying drawings, Figure 1 represents several thread guides attached to the under sides of a finger board, one of the sections of the finger board being turned into upright position, Fig. 2 is a bottom plan view of one of the finger board sections with guide thereon showing the same on an enlarged scale, Fig. 3 is a view of the same in edge elevation, Fig. 1 is a transverse section in the plane of the line AA of Fig. 2, Fig. 5 is a plan view in detail of one of the retaining washers, Fig. 6 is an edge view of the same, Fig. 7 is an enlarged partial view in detail of one of the loops, Fig. 8 is a transverse section of the same, Fig. 9 is a partial plan view of a modified form of loop, Fig. 10 is a transverse section of the same, Fig. 11 is a partial plan view of another modified form of loop, Fig. 12 is a transverse section of the same, and Fig. 13 is an edge view of a modified form of washer.

My present invention consists in providing the thread guide with a shank adapted to interlock with the finger board section producing a frictional grip which will do away with the necessity of a washer or bearing plate interposed between the shank and the finger board section.

Where the finger board section is wood, the shank may be provided with projections capable of piercing the surface of the finger board section sufficient to hold the guide in such position as it may be placed either in a lateral or longitudinal adjustment.

The thread guide contemplated in my present invention consists of wire bent to form an eye 1 through which the thread passes and a shank 2 of loop form made by bending back the wire along itself. This loop portion of the shank is intended to rest fiat on the Specification of Letters Patent.

face of the finger board section 3 and is clamped in position by means of a bolt 4 provided with a nut 5.

The bolt 4 preferably passes through the finger board section 3 and between the parts of the loop 2 of the shank of the guide and there is preferably interposed between the nut 5 and the loop 2, a retaining washer 6 so shaped as to prevent the parts of the loop 2 from spreading and, at the same time, forming a seat for the nut 5 to enable it to press with equal force upon both parts of the loop 2. In the event, however, the wire which forms the guide is sufficiently heavy so that there is no liability of the parts of the loop to spring away from each other, a flat washer such as shown at 7, Fig. 13, may be employed instead of the curved or flanged Washer 6, and it is obvious that the nut 5 might be of sufficient breadth to bear directly on the parts of the loop 2 instead of the flat washer 7.

To hold the guide against any liability of tilting laterally or moving longitudinally on the face of the finger board section 3, the side of the loop 2, toward the face of the finger board section may be provided with spurs 8 and 9 of elongated form such as shown on an enlarged scale in Figs. 7 and 8, or ofshorter form such as shown at 10, Figs. 9 and 10, or the surface may be hatched as shown at 11, Figs. 11 and 12.

The spurs may be conveniently formed by turning up the metal of the loop into a sharp ridge or projection by means of stamping or by means of a metal grooving or gouging tool in such form that the projecting metal will have a sharp edge or point which will indent, to a slight degree, the surface of the finger board.

If the guide were to be used with a metallic finger board section, it would be desirable to hatch the surface of the finger board section similar to the surface shown on the guide, Figs. 11 and 12, in order to have the projections on the guide interlock with those on the finger board.

When the shank of the guide is provided with these projecting points or edges, it will grip the surface of the finger board section with sufficient firmness to prevent accidental displacement whether the shank wire be round in section, as shown in Figs. 8 .and 10, or whether it be flattened as shown in Fig. 12.

In operation, the guide may be readily adjusted to bring its eye in axial alinement with the axis of the spindle by loosening the nut and adjusting the guide on the face of the finger board section to exactly the right position and then screwing up on the nut with sufficient pressure to interlock the projections on the guide with the face of the finger board section.

In using the word interlocking to express the engagement of the shank of the guide with the finger-board head, it is intended to express an actual interlocking of the shank with the surface either by piercing the surface or by indenting it to such a degree as to positively prevent the lateral displacement of the shank with respect to the surface with which it is interlocked until the interlocking pressure of the fastening device is removed.

What I claim is 1. The combination with a finger board, of a thread guide having its shank provided with means for interlocking the shank with the fin er board.

2. T e combination with a wooden finger board, of a thread guide having its shank provided with projections for piercing the surface of the finger board and means for fastening the guide to the finger board.

3. The combination with a wooden finger board of a thread guide having its shank turned back along itself, said shank having means on its inner face for interlocking'it with the finger board and means for fastening the guide to the finger board.

4. The combination With a Wooden finger board, of a thread guide having its shank turned back along itself to form agloop, said loop portion of the shank having means on its inner face for interlocking it with the finger board and means for fastening the guide to the finger board.

5. The combination with a wooden finger board, of a thread guide having its shank turned back along-itself to form a loop, said shank having means on its face for interlocking with the finger board, a Washer arranged to partially embrace the shank to prevent the loops from spreading and a fastening device for holding the parts in assembled adjustment. 1

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two witnesses, this 11th day of December 1906.
